A bamboo shoot is 20 inches tall at day 0 and grows 24 inches each day. which function(s) shown below can be used to determine height, f(n), of the bamboo after n days?
I. f(n)=24n+20
II. f(n)=24n+20(n-1)
III. f(n)=f(n-1)+24 where f(0)=20

Respuesta :

The only correct answer is I. f(n)=24n+20

Answer:

The correct answer is option I

Step-by-step explanation:

Initial height of bamboo [tex]= 20 in\\[/tex]

Height of bamboo grows by [tex]24 in \\[/tex] every day

Let "n" be the number of days

So the height of bamboo after "n" days is

[tex]f(n) = 20 + 24n\\[/tex]

Thus, the correct answer is option I
